1992 Plymouth Acclaim engine block

Hello, with the high mileage your car may need sealing of the engine. It is usually an oil control ring problem which causes too much oil smoke all the time but a stuck pcv valve could also cause excessive crankcase vapors. If you replace the piston rings be sure and do the valve stem seals also. It's a good idea to have the engine's compression tested before attempting any overhaul. And check the fault codes also, they can be tested using Chrysler's DRBIII or DRBII, and a good generic scanner will help you retrieve any codes as if you have the overdrive transmission there may be a problem with that also.
